Carne Asada Street Tacos
Lime, garlic, and a splash of Mexican beer — the marinade that turns a cheap cut of steak into the best taco on your table.
I married into a Colombian family, which means I earned my place at the table the only way that matters: through food. My mother-in-law judges nothing harder than how somebody treats a piece of meat and a pile of fresh herbs — and the day she went quiet over my flautas and reached for a second serving of my pico de gallo, I knew I'd passed. Hispanic food is the love language in our house, and these carne asada street tacos are the recipe my four daughters request more than anything else I make.
Here's what fifteen years in restaurant kitchens taught me about carne asada: the cut matters less than the marinade, and the marinade lives or dies on acid and time. Lime juice, garlic, and a splash of Mexican beer break down a budget flank or skirt steak into something tender, savory, and built for the grill. White onion, cilantro, a hard squeeze of lime, warm corn tortillas — that's it. That's the whole point of a street taco. No sour cream blanket, no shredded cheese avalanche. Just clean, bright, beefy flavor the way it's done from a cart on the corner.
And because real life happens, I'm also giving you my overnight crockpot method — the one I use when I want the meat falling-apart tender and waiting for me by dinner. Grill it for char, crock it for ease. Both are in this post.
WHY YOU'LL LOVE THESE
Cheap cut, restaurant flavor. Flank or skirt steak is affordable, and the beer-lime marinade does all the heavy lifting.
Two methods. Grill for smoky char, or slow-cook overnight for hands-off tenderness.
Authentic, not fussy. Onion, cilantro, lime, corn tortilla. The classic street taco build, nothing hiding the meat.
Family-tested and in-law approved. This is the recipe my Colombian mother-in-law signs off on, and my kids ask for by name.
Naturally gluten-free when made with corn tortillas (verify your brand).

INGREDIENTS
For the carne asada marinade
2 lbs flank steak or skirt steak
Juice of 4 limes (about 1/3 cup)
1/2 cup Mexican beer (Modelo, Pacífico, or Negra Modelo) — or sub orange juice + 1 tbsp white vinegar for a non-alcoholic version
6 garlic cloves, minced
1/4 cup chopped fresh cilantro (stems are fine here)
3 tbsp olive oil
1 tbsp ground cumin
1 tsp chili powder
1 tsp dried oregano (Mexican oregano if you have it)
1 1/2 tsp kosher salt
1 tsp black pepper
Optional: 1 orange, juiced (for a sweeter, more traditional "naranja agria" style)
For the crockpot method (instead of grilling)
Same marinade as above
1 cup beef broth
For serving (the street taco build)
16 small corn tortillas (double up — 8 tacos, two tortillas each)
1 white onion, finely diced
1 bunch fresh cilantro, chopped
2–3 limes, cut into wedges
Optional: salsa verde, hot sauce, Cilantro Lime Crema, or pico de gallo
Ingredient notes:
Flank vs skirt: Skirt is more marbled and more forgiving — my pick. Flank is leaner and a touch cheaper. Both work; don't overcook either.
The beer matters less than you think — any Mexican lager adds malt and a subtle bitterness that balances the lime. The acid is the real engine.
White onion, not yellow. White onion is sharper and cleaner, the traditional street-taco choice.
INSTRUCTIONS
Marinate the steak
In a large bowl or zip-top bag, whisk together lime juice, beer, garlic, cilantro, olive oil, cumin, chili powder, oregano, salt, and pepper (add orange juice now if using).
Add the steak and turn to coat completely. Seal and refrigerate at least 2 hours, ideally 4–8 hours. Don't go past 12 — the acid will start to make the surface mushy.
Grill method (for char)
Pull the steak out 30 minutes before cooking so it comes to room temperature. Pat the surface dry — dry meat sears, wet meat steams.
Heat the grill to high (450–500°F). Grill the steak 3–4 minutes per side for medium-rare, until a deep char forms and the internal temp hits 130–135°F.
Rest the steak on a cutting board, loosely tented, for 5–10 minutes. This is non-negotiable — cutting early dumps all the juice on your board.
Slice against the grain into thin strips, then chop into bite-sized pieces.
Crockpot method (overnight, hands-off)
Add the marinated steak and all the marinade to the crockpot. Pour in 1 cup beef broth.
Cook on LOW for 8 hours (overnight) until fork-tender.
Remove the steak, shred or chop, and return to the juices. Taste and adjust salt.
Build the tacos
Warm the corn tortillas directly over a gas flame or in a dry skillet, 20–30 seconds per side, until soft and lightly charred. Double them up.
Pile on the chopped steak, top with finely diced white onion and cilantro, and finish with a hard squeeze of lime. Serve immediately.
THINGS I TESTED (so you don't have to)
Marinade time: Under 2 hours, the steak tastes flat. Past 12 hours, the surface turns mushy from the lime. The sweet spot is 4–8 hours.
Patting the steak dry before grilling: Skipping this gave me a gray, steamed exterior. Drying the surface is the difference between a sear and a sad.
Slicing against the grain: I tested both directions on the same steak. With the grain = chewy. Against the grain = tender. It matters more than the cut you buy.
Crockpot vs grill: Grill wins on flavor (char + smoke). Crockpot wins on tenderness and convenience. For a weeknight with kids, I crock it overnight without guilt.
COMMON MISTAKES & HOW TO FIX THEM
Steak is tough and chewy. You sliced with the grain, or overcooked it. Slice against the grain, and pull skirt/flank at 130–135°F.
Tacos are watery. You didn't dry the steak before grilling, or you're piling on too many wet toppings. Keep the build clean: onion, cilantro, lime.
Marinade tastes harsh/sour. Too much time in the acid. Cut to 4–6 hours next time, and balance with the optional orange juice.
Tortillas tearing. Cold tortillas crack. Warm them properly and double them up — that's why street tacos are stacked.
Flavor is flat. Under-salted, or you skipped resting the meat. Salt the marinade properly and rest before slicing.
VARIATIONS & SUBSTITUTIONS
No grill? Use a cast-iron skillet or grill pan over high heat — same times, great char.
Non-alcoholic: Swap the beer for orange juice + 1 tbsp white vinegar.
Spicier: Add 1 minced jalapeño or 1 tsp chipotle powder to the marinade.
Different protein: This marinade is excellent on chicken thighs or shrimp (shrimp needs only 20–30 min in the marinade).
Low-carb: Serve in lettuce cups or over a rice bowl instead of tortillas.
WHAT TO SERVE WITH THESE
Build the full spread:
Mexican Street Corn Salad — the sister recipe to this post; creamy, tangy, the perfect cool contrast to the grilled steak
Homemade Pico de Gallo — fresh, bright, and exactly what these tacos want on top
A pitcher of margaritas or a cold Mexican lager (the same one you cooked with)
Cilantro lime rice and a pot of black beans to round out taco night
STORAGE
Fridge: Store cooked steak in an airtight container for up to 4 days. Keep toppings separate.
Freezer: Cooked carne asada freezes well for up to 3 months. Thaw overnight in the fridge.
Reheat: Warm in a hot skillet with a splash of broth to keep it juicy — microwaving makes it rubbery.
Marinade: Never reuse raw marinade. Discard after the steak comes out.
Frequently Asked Questions | FAQ
What's the best cut for carne asada?
After making this more times than I can count, I reach for skirt steak — the extra marbling makes it more forgiving and more flavorful, and it's harder to dry out than flank. Flank is leaner and a little cheaper and still works. Whichever you grab, the real make-or-break isn't the cut, it's slicing against the grain at the end.
How long should I marinate carne asada?
4 to 8 hours is my sweet spot. I've tested both ends: under 2 hours and it tastes flat, past 12 and the lime starts turning the surface of the meat mushy. If you're short on time, 2 hours still beats no marinade — just don't skip the salt.
Why is my carne asada tough and chewy?
Almost always one of two things, and I've done both. Either you sliced with the grain instead of against it, or you took the steak past medium. Pull skirt or flank at 130–135°F and let it rest, then slice thin against the grain — that's what makes it tender enough to fall apart in the taco.
Can I make carne asada in a crockpot?
Yes, and it's my go-to on busy weeknights with the kids. Add the marinated steak, the marinade, and 1 cup beef broth, and cook on LOW for 8 hours — perfect to start before bed. You trade the grill's char for fall-apart tender meat, and honestly nobody at my table has ever complained.
Why are street tacos served on two tortillas?
The double layer holds up to juicy meat without tearing and keeps the whole thing from falling apart in your hand. It's both tradition and pure function — once you've had a single tortilla blow out mid-bite, you'll double up every time.
What kind of beer is best for the marinade?
A Mexican lager like Modelo or Pacífico — the malt and mild bitterness balance the lime acid without overpowering the beef. For a non-alcoholic version, I swap in orange juice plus a splash of white vinegar and it holds up beautifully.
Are carne asada tacos gluten-free?
Yes, when you build them on corn tortillas. Just check that your specific tortilla brand is certified gluten-free, since some add wheat — and skip flour tortillas if GF matters.
